Abstract
Abstract A device for measuring object contours (11) comprises a mirror system with at least three mirrors (13) for reading a contour marked preferably by means of several light sources (12). The contour detection system comprises lenses (14) which render the measurement angle-independent and a collecting optical system (15). The collecting optica) system (15) forms a single faithful image from the sub-images from the respective mirrors (13), which is then imaged, for example, on a television camera (17). The device furthermore comprises an image display device (21) and means (24) for the comparison of contours.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
A device for measuring object contours in which a contour of an object is marked and the marked contour is sensed and measured optically, characterized in that the device for theoptical measurement of a contour comprises a mirror system and a detection system for the formation of a single image of the marked contour on the input surface of an image sensing device.
Claim 2
Independent Claim
63 words
A device for measuring object contours in which a contour of an object is marked and the marked contour is sensed and measured optically, characterized in that the device for theoptical measurement of a contour comprises a mirror system and a detection system for the formation of a single image of the marked contour on the input surface of an image sensing device.
Claim 3
Dependent Claim
36 words
A device as claimed in Claim 1, characterized in that the device includes means for marking a contour comprising at least three light sources which are situated to the side of an object to be measured.
Claim 4
Dependent Claim
64 words
A device as claimed in Claim 1 or 2, characterized in that the mirror system comprises at least three mirrors, each of which has associated with it a lens system for forming an angle-.corrected faithful sub-image of a contour portion on an optical collecting member which forms from the three or more sub-images a focussed, faithful image of the contour on the image-forming device.
Claim 5
Dependent Claim
36 words
A device as claimed in Claim 3, characterized in that the read-out mirror system is of duplicate construction with mutually equal reading angles and mutually equal optical beam path lengths to a common optical collecting member.
Claim 6
Dependent Claim
23 words
A device as claimed in Claim 1, 2 or 3, characterized in that the image-forming device comprises a television camera with a monitor.
Claim 7
Dependent Claim
16 words
A device as claimed in Claim 4, characterized in that a video memory is associated therewith.
Claim 8
Dependent Claim
28 words
A device as claimed in Claim 4 or 5, characterized in that an analog-to-digital converter and a computer are associated therewith for the recording and comparison of contours.
Claim 9
Independent Claim
34 words
A device as claimed in any one of the preceding Claims, characterized in that the detection system is specifically sensitive to a spectral range of radiation by means of which the marking is effected.
Claim 10
Dependent Claim
20 words
A medical irradiation apparatus comprising a device for measuring object contours as claimed in any one of the preceding Claims.
